New User - New Installation

Hi, to all.
I have installed Red Hat, Zaptel, Libpri, Sound and asterisk (maybe ver. 1.2.7 instead 1.2.9 ), anyway… What must I do now to start to work whith my ISDN card? I read all about “The Future of Telephony” manual. But I don’t find nothing enought to begin. Any suggestion will be appreciate. Thank you in advance. bye.
